expand (-3,1)y(1,-2)

expand

(- 3, 1) y (1, - 2)

1 \cdot (- 3 \cdot 1,) y, - 2 (- 3 \cdot 1,) y

Solution steps

(- 3, 1) y (1, - 2)

= (- 3 \cdot 1,) (1, - 2) y

Apply the distributive law:

a (b - c) = ab - a c

a = (- 3, 1) y, b = 1,, c = 2

= (- 3, 1) y \cdot 1, - (- 3, 1) y \cdot 2

= 1 \cdot (- 3 \cdot 1,) y, - 2 (- 3 \cdot 1,) y

\frac{- 3 x ^{2} + 10}{x ^{2} ( x ^{4} - 16 )}

x (1 + x + 1 - x)

\frac{5 s ^{2} - s - 2}{( s + 2 ) ( s ^{2} + 1 )}

(cos (θ) + i sin (θ))^{5}

\frac{b}{s ^{2} ( s + a )}
